acetone butanol fermentation 丙酮丁醇发酵,丁基丙酮发酵
The ginger powder extracted with acetone was 8. 6%. 用丙酮和鲜姜汁制取丙酮粉，得率为8.
The correlation r in methanol,acetone,chloroform and butanol was respectively 0.999 9,0.999 9, 0.998 4 and 0.999 8.The recovery was 96.0%,97.3%,81.1% and 93.9% with RSD 2.7%,1.9%,8.8% and 2.5%,(n=5) respectively. 甲醇、丙酮、氯仿、正丁醇线性关系r分别为 0 .
In this paper we studied the simple history,principle,process and selective method of carrier and medium of production of acetone and butanol with fermentive method of clostridium aceto-butylicum. 本文研究了丙丁菌发酵法生产丙酮和丁醇的简史、原理、过程,以及载体和培养基的选择方法。
